Abstract :
A novel full-bridge soft-switching phase-shifted pulse width modulation (PWM) DC-DC power converter circuit is presented. A tapped inductor filter has been implemented in the proposed converter topology to achieve soft-switching conditions under wide load variation range, to minimise circulating current without using additional resonant circuit and/or auxiliary switching devices. The effectiveness of the proposed soft-switching DC-DC converter is verified by experiment with 2 kW 100 kHz breadboard setup using insulated gate bipolar transistors (IGBTs).
